A black self-inflating mattress from the Outwell 'Sleepin' range

A black self-inflating mattress from the Outwell Sleepin range. Lightweight and compact in design, this foam camping mattress offers reliable performance and comfort with enhanced air flow for good insulation.

This single mattress is made from PFD free 100% polyester and measures 183 x 63 x 5cm (L x W x H) when inflated, packing down to a compact 32 x 21cm when deflated. The self-inflating mattress is supplied with a carry bag for easy storage and portability.

The mattress’ Flat High-Flow (FHF) valve offers fast, reliable inflation and quick deflation, whilst enhancing air flow. The valve is compatible with most electric pumps.


The self-inflating mattress inflates by opening the valve.

1. Initial inflation: It is normal to experience slow self-inflation in a new mattress or if the mattress has been stored rolled away for a long period of time. To overcome this, the valve can be opened and inflated by mouth to assist the foam in taking shape.

2. Normal inflation: When the valve is opened, the mattress will inflate to 80% of normal thickness in approximately two minutes. The valve can be closed and more air blown in to achieve the desired comfort level.

3. Deflating: To remove air from the self-inflating mattress, the valve must be opened, and the mattress fully rolled up. Once all the air has escaped, the valve should be closed, the straps secured and then the mattress can be stowed away in its carry bag.

Please note, to fully remove air from the mattress ready to pack it in its carry bag, Outwell suggests opening the valve and folding the mattress four times to squeeze out most of the air. The valve can then be closed, and the mattress folded lengthwise. It will now be easier to roll the mattress tightly towards the valve. Close the valve before attaching the hook and loop straps.
